⚠️ Please do not run the example without knowing the external load voltage of the PMU,
it may burn your external load,please check the voltage setting before running the example,
if there is any loss,please bear it by yourself
✨ Library specially written for XPowers, supporting CircuitPython, Micropython, Arduino, ESP-IDF
✨ Through esp32,esp32s3 verification,other platforms have not been tested. Due to the many functions of the chip,it cannot be verified one by one.

- Whether DLDO1/DLDO2/RTCLDO2/GPIO1 can be used depends on the chip. It is not available by default. RTCLDO1 has a default voltage, which is generally 1.8V by default. The voltage value cannot be changed or turned off through the register.
